I bought a return Scootbiz ticket and was downgraded on the Singapore to Athens leg of the flight. Scoot is refusing to refund this part of the ticket. They overbooked the flight on the business class section and I got bumped down into economy. Very bad practice of Scoot to oversell tickets and not honour paid premium seats. But what is worst is that they are flatly refusing to refund the donwgrade. After returning from trip, i've wasted time and money from ringing their call centre trying to chase this up. The people at Scoot call centre are incompetent and think of every excuse in the book not to refund you. Like saying things like 'you chose to continue with the flight in economy and therefore accepted the downgrade instead of waiting for the next available business class seat'. They must have been trained to do this. The price difference of one leg of an economy and business ticket is $715. So am now out of pocket by that much. I Will from now on stay away from Scoot. Their business practices are very dirty and disgusting.
